How to create a Shapefile for your Catchment with Google My Maps, how to export it as a KML file and how to attach the file to an e-mail. Please send it to your Regional Coordinator.
Tip: When drawing your map, make sure the Catchment map is a polygon, not a line. To create a polygon, the last point clicked must be on the start point, then double-click to finish the polygon. This will create a polygon and not a line.
